GOOGLE TALK OFFLINE SETUP

Google Talk is an instant messaging service that provides both text and voice communication. The instant messaging service is colloquially known as "gtalk" or "gchat" to its users, although Google does not endorse this name.

FEATURES   :

Ø Google Talk used XMPP to provide real-time extensible messaging and presence events, including offline messaging and voice mailing. Google Talk supported messaging with any service provider that supports the XMPP protocol.

Ø Google Talk was integrated into Gmail. Users can send instant messages to other Gmail users. As it works within a browser, the Google Talk client does not need to be downloaded to send instant messages to Gmail users.

Ø It is possible to place and receive phone calls from within gmail by using Google Talk. In order to receive calls, however, the user must upgrade to a full Google Voice account. Initially, users outside of the US cannot upgrade to a full Google Voice account and cannot receive phone calls in Gmail.

Ø Google introduced offline messaging to Google Talk. This allows users to send messages to their contacts, even if they are not signed in. They will receive the messages when they next go online even if the user who has sent it is offline. This only works between gmail-accounts though, and doesn't work between Google Talk servers and other XMPP servers.
